Duncan Sands e7a9ac929f Fix some load/store logic that would be wrong for 
apints on big-endian machines if the bitwidth is
not a multiple of 8.  Introduce a new helper,
MVT::getStoreSizeInBits, and use it.

Evan Cheng 797d56ff17 Much improved pic jumptable codegen: 
Then:
        call    "L1$pb"
"L1$pb":
        popl    %eax
		...
LBB1_1: # entry
        imull   $4, %ecx, %ecx
        leal    LJTI1_0-"L1$pb"(%eax), %edx
        addl    LJTI1_0-"L1$pb"(%ecx,%eax), %edx
        jmpl    *%edx

        .align  2
        .set L1_0_set_3,LBB1_3-LJTI1_0
        .set L1_0_set_2,LBB1_2-LJTI1_0
        .set L1_0_set_5,LBB1_5-LJTI1_0
        .set L1_0_set_4,LBB1_4-LJTI1_0
LJTI1_0:
        .long    L1_0_set_3
        .long    L1_0_set_2

Now:
        call    "L1$pb"
"L1$pb":
        popl    %eax
		...
LBB1_1: # entry
        addl    LJTI1_0-"L1$pb"(%eax,%ecx,4), %eax
        jmpl    *%eax

		.align  2
		.set L1_0_set_3,LBB1_3-"L1$pb"
		.set L1_0_set_2,LBB1_2-"L1$pb"
		.set L1_0_set_5,LBB1_5-"L1$pb"
		.set L1_0_set_4,LBB1_4-"L1$pb"
LJTI1_0:
        .long    L1_0_set_3
        .long    L1_0_set_2

 2007-11-09 00:47:10 +00:00
Ted Kremenek 1d9406c1ca Updated Deserializer class to provide more information about the current 
block that is being visited in the bitstream.  The client can also now
skip blocks before reading them, and query the current abbreviation number
as seen from the perspective of the Deserializer.  This allows the client
to be more interactive in the deserialization process (if they so choose).

Owen Anderson 65d2fcdd2a This preserves critical edge breaking.

 2007-11-08 22:20:23 +00:00
Ted Kremenek 67135ebaff Added typedef "SerializedPtrID" to represent the pointer handle written to disk 
instead of just using "unsigned".  This gives us more flexibility in changing
the definition of the handle later, and is more self-documenting.

Added tracking of block stack in the Deserializer.  Now clients can query
if they are still within a block using the methods GetCurrentBlockLocation()
and FinishedBlock().

Owen Anderson 0be8c1dafe Add the majority of machine-level critical edge breaking pass. Most of this was written by Fernando, cleanup and updating to TOT by me. 
This still needs a bit of work, particularly to handle jump tables properly.

Dale Johannesen 1b9de4dd6f Complete conditionalization of Dwarf reg numbers. 
Would somebody not on Darwin please make sure this
doesn't break anything.  Exception handling failures
would be the most likely symptom.

Evan Cheng dd71a5c37b When the allocator rewrite a spill register with new virtual register, it replaces other operands of the same register. Watch out for situations where 
only some of the operands are sub-register uses.

Duncan Sands f042e862fd At the point of calculating the shift amount, the 
type of SV has changed from what it originally was.
However we need the store width of the original.

Evan Cheng 2dbffa4e76 Add pseudo dependency to force two-address instruction to be scheduled after
